If you have kids and haven't planned your transit through Amsterdam, here's why you should stop being so silly (yes yes it does require you fly KLM, but I swear it's worth it).
There's a whole big room of these little "pods".
Yes that is an actual CRIB you see.
The library. See the whole shelf of "children's books"? See that it's written in English? There's even more books for adults, as of course you didn't pack reading material because all your time is spent making sure the little people don't melt down.
The "treehouses". Climbing, sliding, running. Things that wear out little travelers and give you a shred of hope they will sleep on the next leg.
